Summary: | It is frequently observed that the queue lengths on the approach roads at a signalised
intersection are imbalanced during peak hours and in many cases traffic marshall has
to control the intersection manually. This problem is partly due to the inability of the
conventional system to be optimised and to get the actual traffic demand. To
overcome these two problems, the traffic control system developed in this project
adopts vehicle actuated control, optimised control and traffic marshall emulation
control during low, high and congested traffic demand respectively. The system
utilised a video detection system as the sensor to detect the real traffic demand.
Experimental data show that the control system. is found to reduce the sum of queue
length 33% as compared to the conventional system. During congested period
proposed system reduced queue length by 9% and delay by 10% as compared to
manual control by traffic marshall |
